Redesign the way -aspect option is handled. This is done by making
ffmpeg read the sample aspect ratio set in the corresponding input
stream by default, and overriding it using the value specified by
-aspect.
If the output display aspect ratio is specified with -aspect, it is
set at the end of the filterchain, thus overriding the value set by
filters in the filterchain.
This implementation is more robust, since does not modify the
filterchain description (which was creating potential syntax errors).
There is no need to have 2 encoders, the input sample format can,does and should choose which is used

Prefer parse_number_or_die() over atoi()/atol() parsing for the options:
-pass, -top, -vc, and -qscale.
Improve input validation.

I was using the wrong value to track the position of the parser in the
stream. For an error-free stream, the size of the frame and number of
bytes consumed will be the same, but in an error situation they can
diverge.

swscale: fix "ISO C90 forbids mixed declarations and code" warning
swscale: fix compilation with --enable-runtime-cpudetect
swscale: correct include path to fix ppc altivec build
swscale: simplify rgb2rgb templating
swscale: simplify initialization code
swscale: further cleanup swscale.c
swscale: partially move the arch specific code left
swscale: move away x86 specific code from rgb2rgb
None of above is merged, the changes are not yet ready they add over 2000 lines of duplicated code and a few bugs

Also add inttypes.h #include for PRId64 macros.
This fixes the following warnings:
libavformat/xwma.c:147: warning: too many arguments for format
libavformat/xwma.c:151: warning: too many arguments for format
The warning is printed with loglevel error because the output
stream is known to be broken.
Also warn if no channel layout was provided for multichannel input.

PPC and x86 code is split off from swscale_template.c. Lots of code is
still duplicated and should be removed later.
Again uniformize the init system to be more similar to the dsputil one.
Unset h*scale_fast in the x86 init in order to make the output
consistent with the previous status. Thanks to Josh for spotting it.
Keep only the plain C code in the main rgb2rgb.c and move the x86
specific optimizations to x86/rgb2rgb.c
Change the initialization pattern a little so some of it can be
factorized to behave more like dsputils.
The functions are already av_ prefixed and sha1 header is already provided.
Install libavutil/{aes,sha}.h

ff_get_wav_header is reading data from a WAVE file and then uses it
(without validation) to malloc a buffer. It then proceeded to read
data into the buffer, without verifying that the allocation succeeded.
To address this, change ff_get_wav_header to return an error if
allocation failed, and adapted all calling code to handle that error.

The mpegts muxer does not set the stream time base using
av_set_pts_info, but expects it to have the default value of 1/90000.
If the calling code changes stream pts before writing the header,
other muxers override the time base at that point (like mpegenc.c).

Also rename the incorrectly named enc_bitrate to enc_mode, use the
enc_bitrate variable for storing the last chosen bitrate.
This avoids continuous warning log messages if not using an
exactly matching bitrate, while still allowing changing bitrate
at any point.
